Abstract (en)
[origin: US2016175939A1] A surface-coated tool includes a substrate and a coating film formed on the substrate. The coating film includes an alternate layer in which one or more A layers and one or more B layers are alternately stacked. The A layer and the B layer each have a thickness not smaller than 2 nm and not greater than 100 nm. An average composition of the A layer is expressed as TiaAlbSicN (0.5<a<0.8, 0.2<b<0.4, 0.01<c<0.1, a+b+c=1), an average composition of the B layer is expressed as TidAleSifN (0.4<d<0.6, 0.3<e<0.7, 0.01<f<0.1, d+e+f=1), and a condition of 0.05<A-D≰0.2 AND 0.05<E-B≰0.2 is satisfied.
